Seems Dahua is a recognized brand. So, I've hopped on amazon and looked to buy a few 3mp cams, a poe switch.. And dvr. However, it looks like all the dvrs have a single lan port and all the inputs are coax. Is there a known setup that will be around or below 500 for two cameras, dvr, switch, and other miscellaneous parts? Thanks so much! Rob
